29 Jan 20259 minutes to read

This section briefly explains about how to include Blazor Bullet Chart component in your Blazor Web App using Visual Studio.

Prerequisites

Create a new Blazor Web App in Visual Studio

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion® Blazor Extension.

You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.

Install Syncfusion® Blazor Bullet Chart NuGet in the App

To add Blazor Bullet Chart component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.BulletChart.

If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion® Blazor components NuGet packages within the client project.

Alternatively, you can utilize the following package manager command to achieve the same.

Install-Package Syncfusion.Blazor.BulletChart -Version 28.2.3

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Create a new Blazor Web App in Visual Studio Code

You can create a Blazor Web App using Visual Studio Code via Microsoft Templates or the Syncfusion® Blazor Extension.

You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.

For example, in a Blazor Web App with the Auto interactive render mode, use the following commands.

dotnet new blazor -o BlazorWebApp -int Auto
cd BlazorWebApp
cd BlazorWebApp.Client

NOTE

For more information on creating a Blazor Web App with various interactive modes and locations, refer to this link.

Install Syncfusion® Blazor BulletChart and Themes NuGet in the App

If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion® Blazor components NuGet packages within the client project.

  • Press Ctrl+` to open the integrated terminal in Visual Studio Code.
  • Ensure you’re in the project root directory where your .csproj file is located.
  • Run the following command to install a Syncfusion.Blazor.BulletChart NuGet package and ensure all dependencies are installed.
dotnet add package Syncfusion.Blazor.BulletChart -v 28.2.3
dotnet restore

NOTE

Syncfusion® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Register Syncfusion® Blazor Service

Interactive Render Mode Description
WebAssembly or Auto Open ~/_Imports.razor file from the client project.
Server Open ~/_import.razor file, which is located in the Components folder.

Import the Syncfusion.Blazor and Syncfusion.Blazor.Charts namespace.

@using Syncfusion.Blazor
@using Syncfusion.Blazor.Charts

Now, register the Syncfusion® Blazor Service in the ~/Program.cs file of your Blazor Web App.

If the Interactive Render Mode is set to WebAssembly or Auto, you need to register the Syncfusion® Blazor service in both ~/Program.cs files of your Blazor Web App.

...
...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents()
    .AddInteractiveWebAssemblyComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....
...
using Syncfusion.Blazor;

var builder = WebAssemblyHostBuilder.CreateDefault(args);
builder.Services.AddSyncfusionBlazor();

await builder.Build().RunAsync();

If the Interactive Render Mode is set to Server, your project will contain a single ~/Program.cs file. So, you should register the Syncfusion® Blazor Service only in that ~/Program.cs file.

...
using Syncfusion.Blazor;

var builder = WebApplication.CreateBuilder(args);

// Add services to the container.
builder.Services.AddRazorComponents()
    .AddInteractiveServerComponents();
builder.Services.AddSyncfusionBlazor();

var app = builder.Build();
....

Add script resources

The script can be accessed from NuGet through Static Web Assets. Include the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

NOTE

Check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Add Syncfusion® Blazor Bullet Chart component

Add the Syncfusion® Blazor Bullet Chart component in the ~Pages/.razor file. If an interactivity location as Per page/component in the web app, define a render mode at the top of the ~Pages/.razor component, as follows:

Interactivity location RenderMode Code
Per page/component Auto @rendermode InteractiveAuto
  WebAssembly @rendermode InteractiveWebAssembly
  Server @rendermode InteractiveServer
  None —

NOTE

If an Interactivity Location is set to Global and the Render Mode is set to Auto or WebAssembly or Server, the render mode is configured in the App.razor file by default.

@* desired render mode define here *@
@rendermode InteractiveAuto
<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="0" Maximum="300" Interval="50">
</SfBulletChart>

@code{
    public class ChartData
    {
        public double FieldValue { get; set; }
        public double TargetValue { get; set; }
    }
    public List<ChartData> BulletChartData = new List<ChartData>
    {
        new ChartData { FieldValue = 270, TargetValue = 250 }
    };
}
  • Press Ctrl+F5 (Windows) or ⌘+F5 (macOS) to launch the application. This will render the Syncfusion® Blazor Bullet Chart component in your default web browser.

<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="0" Maximum="300" Interval="50" Title="Revenue">
</SfBulletChart>

Adding ranges

Add ranges by using the BulletChartRangeCollection to measure the qualitative state by observing the distance between each range.

<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="
0" Maximum="300" Interval="50" Title="Revenue">
    <BulletChartRangeCollection>
        <BulletChartRange End=150> </BulletChartRange>
        <BulletChartRange End=250></BulletChartRange>
        <BulletChartRange End=300></BulletChartRange>
    </BulletChartRangeCollection>
</SfBulletChart>

Adding tooltip

Use the tooltip to show the measured values by setting the Enable property to true in the BulletChartTooltip.

<SfBulletChart DataSource="@BulletChartData" ValueField="FieldValue" TargetField="TargetValue" Minimum="0" Maximum="300" Interval="50" Title="Revenue">
    <BulletChartTooltip TValue="ChartData" Enable="true"></BulletChartTooltip>
    <BulletChartRangeCollection>
        <BulletChartRange End=150> </BulletChartRange>
        <BulletChartRange End=250></BulletChartRange>
        <BulletChartRange End=300></BulletChartRange>
    </BulletChartRangeCollection>
</SfBulletChart>
